My invention relates to railway trolling stock and consists in novelconstruction 0 various features of vehicles'frame structure and isparticularly-adapted for use in locomotive underframing in which all,

comotives and I illustrate such embodiment of my invention in theaccompanying drawin a locomotive 'bed of the one-piece type in whichside. frame elements 1 have formed integrally therewith other elementssuch as the in s.

%)ne of the objects of my invention is to improved center plateconstruction and tounite the same with the boiler saddle and adjacentparts of the locomotive, preferably in a one-piece casting.

v Another object of my invention 15 tolpro- .vi-de an improved frontdeck structure adapted to mount the pumps for air and feed water with aminimum number of fastening devices and insuch a manner that the pumpsfrom inj ury by. foreign articles, which may collide tion fromair-currents.

Another object of my invention is to providelocomotive framing'withsuitable means for cooperating with a lateral motion driving box devicewhereby of delay and labor.

Other detailed objects of my invention are same being broken away toavoid duplica-- tion.

, My invention is shownasbeing embodied steam cylinders 2, the -steamcontrol valve chambers 3, the boiler saddle 4 ,the front deck plate 5,andpedestal jaws 6.

, .F v rmed integrally with the'steam cylindersand theboile'r saddle areinwardly and downwardly projecting elements 7 carrying between them adownwardly projecting circular, dowel-like member 8.which forms the bodyofthe locomotive center plate but is provided with a renewable cupShaped wear plate Qadapted to fit into the corresponding center platemember 10 of the 'truck'll "(see Fi ure 3), The usual construction is toprovi e a separate center plate on underside of cylinder casting whichcasting is bolted to the frame member and on account; of the height ofthe cylinder casting, a deep center plate memberis necessary. Thestructure shown eliminates the necessity of providing a deep centerplate and there are no bolts to be kept tightior other difiicultyaccompanying the attachment of acenter plate to the locomotive framing.Preferably, the wear plate 9 issecured to the dowel member 8 byspot-welding, as indicated at W.'

Tliefront deck-5 isprovided with upstanding brackets "12 and 13' adaptedto mount 7 pumps such as the air pumps indicated at 14 vor thefeed waterpumps indicated at 15. It

, will be noted that the rear ends 16 of these brackets merge with theinwardly extending front walls17 of the cylinder and cylinder valvestructure whereby the brackets Hand '13 are braced for a substantialdistance above the front deck. Suitable brackets 18 for mounting orbracing a ilotbeam 19 (which y with the frontdeck A desirable,particularly in co Adjacent to the pedestal jaw 6 the sides 1 of or'applied thereto) are formed into ally with the deck and are extendedupwar 1y, as indicated at 20, in front of the space occupied by thepumps 14 and 15, and serve to protect the latter against any'objectwhich may be struck by the locomotive and also serve to deflect aircurrents from the umps which is id weather.

the bed are connected by integral cross ties 21 and each of these ties21 is provided with a 'fiange 22 adapted to mount a wear plate 23against which may bear the vertical arm 24 of I box does not form a bellcrank lever mounted on a driving box 25 and carrying the spring saddle26. The mounting of the spring saddleon the driving art of m invention.

The contacting aces of t e flange 22 and the wear plate 23 are providedwith intercugaging elements such as the lip 27 and the ad acent edge ofthe wear plate, whereby relative rotation of the wear plate and flan eis prevented. The wear plate is retains in v position u on flange 22 bymeans of the trun- 25' end and retainin nuts 29. I prefer'topronion-like e ement 28, having a threaded inner vide asuitable shim 30between plate 23 and than 22 and, b use of shims of difi'erent thicness, it will possible to adjust the normal lateral movement of thedrivin box.

Such adjustment can be readily made with the U-shaped shim detailed inFigure 8 by loosenelements 0 vious structures.

in the usual manner.

ing nuts 29 and lowerin the shim and inserting a new shim which isthicker or thinner than the one removed. It willbe noted that suchadjustment can be made from below and does not reguire the disassemblyof any other the device and does'not require the machining of any partof the lateral motion device, such as has been required in prevwhich ishere shown as an annular ring surrounding the dowel member 34 but notcovering the bottom of member 34:. This will be preferable in some typesof construction and may be used, if desired. Tha -plate 33 is preventedagainst rotation on member 34 by means of spot-welding orflby othersuitable means such as'referred to in my copendin application SerialNumber 27 0,950, file April. 18,1928. y In each of the forms of mycenter plate structure the-dowel member and wear plate are arranged topermit free passage therethrough of the center pin so that the same maybe inserted or removed in the usual manner. This is provided for by theenlarged opening indicated at X.

It is also to-be understood that the above arrangement of dowel memberand wear plate can be used for other railway vehicle underframes thanlocomotive underframes.

Other variations in'th'e details of my invention may be made withoutdepartin from the spirit thereof and I contemplate t e exclusive use ofsuch modifications as come within the scope of my claims.
